Typically, grouping is used to apply some sort of aggregate function for each group. [1] [2] The result of a query using a GROUP BY statement contains one row for each group. This implies constraints on the columns that can appear in the associated SELECT clause. As a general rule, the SELECT clause may only contain columns with a unique value ...
Formulas in the B column multiply values from the A column using relative references, and the formula in B4 uses the SUM() function to find the sum of values in the B1:B3 range. A formula identifies the calculation needed to place the result in the cell it is contained within. A cell containing a formula, therefore, has two display components ...
The listagg function, as defined in the SQL:2016 standard [2] aggregates data from multiple rows into a single concatenated string. In the entity relationship diagram , aggregation is represented as seen in Figure 1 with a rectangle around the relationship and its entities to indicate that it is being treated as an aggregate entity.

Another method of grouping the data is to use some qualitative characteristics instead of numerical intervals. For example, suppose in the above example, there are three types of students: 1) Below normal, if the response time is 5 to 14 seconds, 2) normal if it is between 15 and 24 seconds, and 3) above normal if it is 25 seconds or more, then the grouped data looks like:
SQL: New window functions FIRST_VALUE and LAST_VALUE; SQL: New date/time conversion functions for TIMESTAMPL, DATS and TIMS; SQL: New time stamp functions UTCL_CURRENT, UTCL_ADD_SECONDS, and UTCL_SECONDS_BETWEEN; SQL: New date functions DATN_DAYS_BETWEEN, DATN_ADD_DAYS, and DATN_ADD_MONTHS; SQL: New additions after the ORDER BY clause: NULLS ...
